The Red Bull RB5 is a Formula One racing car designed by the Red Bull Racing team for the 2009 Formula One season. It was driven by Sebastian Vettel, who drove for Red Bull's sister team Toro Rosso in the 2008 season, and Mark Webber. The car was launched on 9 February 2009 at the Circuito de Jerez in Spain.

The car gave the team its first pole position, first win and first ever 1–2 finish at the 2009 Chinese Grand Prix. Over the course of the season the car turned out to be competitive as it won 6 out of 17 races, with Vettel winning four races and Webber winning two. As a result, the team finished 2nd in the Constructors' Championship standings behind Brawn GP and Vettel finished second in the Drivers' Championship standings behind Jenson Button.

New rules in place for the 2009 season required cars to have narrower and higher rear wings and wider and lower front wings, designed to reduce air disturbance to following cars and hence make overtaking easier. Slick tyres were re-introduced into Formula One, after being absent since 1998. This was expected to increase the RB5's tyre grip by about 20%.

There was a possibility that the RB5 could feature a Kinetic Energy Recovery System (KERS), which would allow energy which would otherwise be wasted while braking to be re-used in set amounts per lap, via a boost button on the driver's steering wheel. This was the result of new rules for the 2009 season. Red Bull originally attempted to develop their own system, but a factory fire resulting from overheated batteries stalled progress. In January 2009 Red Bull announced that they would use an identical KERS system to the Renault team, in an extension of the existing customer engine deal between the teams. However the RB5 never did race with KERS.

2009 season

Launch

The RB5 was launched later than most of its rivals, to allow a longer development time at the expense of a shorter testing time. Red Bull expected the RB5 to be more competitive than its predecessor, the RB4, which achieved a single podium in 2008. Vettel was optimistic when questioned about the car's potential:

"Obviously it's not correct sitting here and say I am going to win the world championship. I want to, but we need to see. We need to see how we are going, where we are in comparison to the others. I believe that the new rules could give a chance to teams like us to close the gap to the front but the favourites are Ferrari and McLaren, no doubt."

Sebastian Vettel, who (since joining Scuderia Toro Rosso) makes it a habit to name his racing cars, named his Red Bull RB5 'Kate' and after crashing it at Melbourne's Albert Park, he named his new chassis 'Kate's Dirty Sister'.

Testing

Initial tests of the RB5 at Jerez were halted when high gearbox oil temperatures were detected. When the issue was resolved the RB5 was the quickest 2009 specification car at Jerez, where Vettel was faster than the equivalent Williams, McLaren and Renault cars. Webber returned to the cockpit after breaking his leg while cycling in November 2008; he completed 83 laps in the RB5, around the distance of a Grand Prix, and reported no problems whilst lapping faster than Vettel the previous day.

Newey gift car

In July 2010, Red Bull gifted designer Adrian Newey a complete RB5 car as a "thank you" gift for turning Red Bull into a title-challenging team. Newey first drove the car at the hill at the Goodwood Festival of Speed.
